A brother and sister are behind bars after allegedly having sex in a tractor trailer parked in a church parking lot.

Police say Christopher Buckner, 20, and her half-brother Timothy Savoy, 25, admitted to committing incest three times in a church parking lot outside of Savannah, Georgia after watching the Ryan Gosling romance “The Notebook.”

(For those not familiar with the cult film, it doesn’t have a happy ending).

Police were alerted to the pair’s antics early on Tuesday morning after responding to a call about a prowler in the area.
